History
The district was created on 13 December 1970 as a minor district (king amphoe) with territory from Wichian Buri district. It was upgraded to Si Thep District on 8 August 1976.[3]
Si Thep is on a dry highland surrounded by waterways and floodplains bordered by mountains on both sides. To ensure sufficient water for city use, ancient Si Thep had an elaborate system of ponds, tank moats, and a hydraulic system to bring water from higher grounds to sustain the city.[1]
The district is divided into seven sub-districts (tambons), which are further subdivided into 93 villages (mubans). The township (thesaban tambon) Sawang Watthana covers parts of tambon Sa Kruat. There are seven tambon administrative organizations (TAO).
